ori inal application filed October 29, 1909, Serial No 525,021. Divided and this application filed November so, 1910. Serial No. 594,995.

into a thin falling-stream of stock-food or dry base material whereby. the latter be comes thoroughly impregnated with the former; then heating, stirring, and conveying the impregnated material; and then finally, gradually drying the material and reducing the temperature thereof by means of suitable conveyers and cool suction air blasts, the latter being carried over the material as the same is passed through said conveyers.

In the accompanying drawings I have shown a convenient apparatus for carrying out the process herein described and claimed.

This apparatus is made the subject of my application for Letters Patent for improvements in machinesfor impregnating stockfoods, filed October 28, 1909, Serial No. 525,021, of which this application is a divisional part.

Referring to the accompanying drawings forming a part of this specification, Figure 1 is a front elevation of a machine or apparatus for carrying out my improved process.

Similar numerals of reference designate like parts throughout-all the figures of the draw s. 1 u The improved machine ,or apparatus, in its present embodiment com rises a storage bln 1, into which the stockood or dry base is provided with a depending hopper portion 1, provided at its lower end with an inclined shaker board or plate 3, adapted when the machinery is operated, to be reciprocated by means of an eccentric shaft 4, and connecting rod 5. When the machinery is in operation the shaker plate 3, is adapted to distribute and feed the stock-food or base material in a thin longitudinally extending streamalong the edge 3, of the plate where it falls into one end of the heater-mixer 6, to be heated and conveyed as hereinafter described. I

- After the molasses has been properly heated in the kettle or tank 2, preferably at a temperature of from 210 to 220 Fahrenheit and the machinery started, it;is conducted through the conduit pipe 7, by opening the valve 8, and the hot molasses is permitted to enter the longitudinally extending chamber 9, of the valve body 10, carried upon the end of the conduit pipe The .valve body 10, extends horizontally g'the full width of the adjacent end of the heatermixer 6, and is provided with longitudinally extending nozzle portion 10, adjacent to the falling stream of. food to be treated, and said nozzle portion is adapted to distribute and project the atomized molasses into the falling stream of stock-food or basematerial.

The character and quantity of'the atom- I ized stream of molasses passing out of the longitudinal slot 11, of the nipple portion 10 is controlled and regulated by means of a longitudinally extending hollow wedge shaped or tapered movable valve 12, mounted in ways 13, within thesvalve body '10, said movable valve having its tapered portion 12 adapted to .be seated within the longitudinal recess or channel portion 11:, of the valve body. The movable valve 12, is provided with a-longitudina'l slot 13, at the apex of its tapered portion 12 said slot registering with and being adjacent to the slidably mounted in the rear portion of the valve body. The air inlet pipe or stem 15, is connected to a suitable air pipe or hose communicating with a suitable air compressor adapted to force compressed air into air chamber 14, and out through the longitudinal slot 13, whereby the hot molassesin passing out through the longitudinal slot 11, of the nozzle portion of the valve body will be thoroughly atomized and projected into the adjacent falling stream of stockfood.

The valve body 10 is provided at its ends with threaded openings through which the movable valve 12, may be inserted or removed, said threaded openings being closed by ineans of threaded plugs 16. The movable valve 12 is adapted to be moved or shifted to and from its open or closed positions by means of threaded thumb bolts 17, extending rearwardly and mounted in suitable threaded openings in the rear portion of the valve body as shown. The slidably mounted air inlet pipe 15, preferably extends through an exteriorly threaded boss 18, adapted to contain a packing-gland retained in position by means of a packing nut 19.

The heater-mixer 6, contains a V-shaped trough 20, surrounded by a series of steam heating pipes 21. The stock-food or base material after being subjected to the spray of molasses and afterv falling into the end of the heater-mixer, is carried along in the V'shaped' trough by means of a screw conveyer 22, mounted on a driving shaft 23. The stock-food or base material, as carried along in the trough 20, is heated from the steam pipes 21, and the heat generated in the chamber 24, intermediate the trough 20, and the walls of the mixer 6, is adapted to communicate with the receiving end of conveyer trough 20, in the present instance, by means of a conduit pipe 25, having its end 25 intersecting the front wall of the heatermixer as shown most clearly in Fig. 6 of the drawings. An apron 26, is preferably formed in the trough 20, above the screw conveyer 22, and the hot air is drawn from .the receiving 'end of the heater-mixer through the stream of falling base material toward the discharge end of the heatermixer by means of a suction trunk 27 communicating with a suction or blower fan in the fan casing 28. The-cold air passes into the heater-mixer 6, through the air inlet openings D and is there heated by passing over and about the steam pipes 21, where it is heated and utilized as above described. One end of the shaft 23, is provided with a driving pulley 29, adapted to carry a belting communicating with a suitable source of power and the other end of the driving shaft is provided with a sprocket wheel 30, carrying a sprocket chain 31, passing over a second sprocket wheel 32, above, which latter operates a suitable elevator chain or belt in the vertically arranged elevator boots 33. The shaft 23 is provided with a second sprocket wheel adjacent the driving pulley 29, carrying a second sprocket chain 34, passing over a sprocket wheel 35, below. The sprocket wheel 35, drives a second screw conveyer located in a conveyer box 36. The receiving end of the conveyerbox 36, is provided with a vertical feed box or spout 37, which receives the feed from the discharge end of the heater-mixer 6, above. The feed, as received at the receiving end of the conveyer box 36, is carried by the screw conveyer to the opposite end of the conveyer box where it is discharged and falls through a vertical spout orb 0x 38, into the receiving end of a second conveyer box 39. The feed as discharged in this conveyer box is conveyed by a screw conveyer, similar to those above described, to the opposite end of the conveyer box 39, where it is discharged through a discharge spout 40, intersecting the lower ends of the elevator boots 33. The screw conveyer in the conveyer box 39, is operated by a sprocket wheel 41, carrying a sprocket chain 7 extending along the spout or box 36, and

intersecting the upper end of the discharge spout or box 38.

The suction of the air in the suction trunk 27, may be regulated by means of a suction regulator slide valve 47. at the upper end of the suction trunk and a small cold air inlet opening 48, is provided below to admit a certain amount of cold air into the suction trunk 27, to mix with the Warm air therein and carried to the fan in the fan casing below. The finished feed after being carried to the head of the elevator boots 33,

above is discharged through the discharge pipe 49, leading to the sacker. The floor lines are indicated by the lines A, B, and C. The eccentric shaft 4 is suitably connected by means of any suitable and convenient gearing or driving mechanism to the drivlng shaft 23, carrying the main driving pulley 29.

As the stock-food is fed in a thin longitudinally extending stream along the edge 3*, of the inclined shaker-board 3, and falls into the end of the heater-mixer 6, it is impregnated with hot atomized molasses projected into the falling stream by means of the longitudinally extending atomizing nozzle portion 10 of the valve body 10. A hot-air blast passes through the falling stream of stock-food from the conduit pipe 25, and the stock-food in the heater-mixer 6, is further heated by the passage of said hot-air over the'stock-food and the heating of the Walls of the V -shape'd trough 20, by means of the steam heating pipes 21. When the stock-food reaches the discharge end of the heater-mixer 6, it is discharged vertically through a vertical spout 37 into the receiving end of a conveyer-box 36, below, and as the food falls through the spout 37, it is cooled to a certain degree by means of a cold air blast passing out of the branch of the cold air discharge pipe 45, leading from the fan casing 28.

The stock-food is conveyed to the opposite end of the conveyer-box 36, by means of a second screw conveyer, and when it reaches the opposite or discharge end of the conveyer-box 36, it falls vertically through the vertical spout 38, where it is further cooled by a second cold air blast passing out of the intersecting cold air conduit 46, extending along the 'conveyer-box 36. By the time the stock-food has reached the receiving end of the conveyer-box 39, it has been sufficiently cooled and is conveyed through the conveyerbox by means of a third screw conveyer which discharges the stock-food into the intersecting lower ends of the elevator-boots 33.

From the foregoing description taken in by Letters Patent is,

1. The process of making or mixing stockfoods, consisting in simultaneously projecting intersecting streams of base materialand hot atomized molasses, the former being in the form of a falling stream intersected by the latter.

2. The process of making or mixing stock-foods, consisting in (l) impregnating dry base material with hot atomized molasses, (2) stirring and heating said impregnated material, and (3) conveying drying and cooling the same by air blasts.

3. The process of making or mixing stock-foods, consisting in projecting atomized heated molasses into a falling stream of base material, (2) gradually heating, and (3) gradually cooling the impregnated material in a stream subjected to air blasts.

4. The process of making or mixing stock-foods, consisting in (l) heating molasses and atomizing and projecting the same into a falling stream of base ma-* teri'al, (2) heating and stirring the impregnated base material, and drying and stirring the same in suction air blasts of reduced temperature.
